For centuries extracts have been used as elixirs for all sorts of ailments. Individuals would seek out certain plant materials that were known for their beneficial properties and ferment them to extract the desired benefits. This same technology can be used to extract properties from plants such as geranium to make a citronella extra for keeping away mosquitoes. Hot peppers and garlic are also known for their pest-deterring properties. If you incorporate companion planting (basil with tomato), you may find a winning combination to give the effect you want. You can use nearly any plant material known for some benefit in this extract, whether it is for companion planting, pesticide, anti-fungal effects, or micronutrients.

Weeds and other green material can be recycled into an organic foliar spray and insect repellent. During fermentation EM•1® is able to ferment weeds and extract organic acids, bio-active substances, minerals, and other useful organic compounds from these materials which are able to promote plant growth and repel diseases or insects.
